How long has it been since COVID-19 started?

Exposure, the first symptom, and the positive test are different dates. Write down each one if known, then note when fever, cough, breathing trouble, fatigue, taste loss, or smell loss began. Symptoms can appear at different times and may improve at different rates. If symptoms continue or return after the initial illness, a clinician can consider Long COVID alongside other explanations rather than assuming every later symptom has the same cause.

Keep a short daily record of temperature if advised, breathing, energy, sleep, eating, drinking, and activity. Mark improvements and setbacks, including symptoms triggered by exertion. Bring the dates and any test results to an appointment. Continue infection-control advice relevant to your current situation and avoid strenuous activity while acutely unwell. Use prescribed treatment as directed.

Arrange care when symptoms are worsening, returning after improvement, or limiting work, movement, sleep, food, or fluids. Seek urgent help for severe breathlessness, chest pain, fainting, new confusion, or sudden weakness. The exact calendar date matters less than the direction of symptoms and whether basic functions are affected.

Which date should we use as my illness start? Does my symptom pattern suggest another problem? How should I pace activity now? What signs mean I need urgent assessment?
